Description / 0805 SMD UV / Purple - Ultra Bright LED

The 0805 UV Purple SMD LED (2.0 × 1.25mm, metric 2012) is the most hobbyist-friendly SMD size — large enough to comfortably hand-solder with a standard fine-tip iron, small enough to fit on any modern PCB layout. The sweet spot between easy handling and compact footprint. UV/Purple output creates blacklight effects — used in art, cosplay props, escape room builds, and decorative accent lighting.

The most hobbyist-friendly SMD size — large enough to hand-solder comfortably with a standard fine-tip iron.

Common uses:

  • Mechanical keyboard backlight and per-key indicator repair — the most common indicator LED size in custom keyboard PCBs (r/MechanicalKeyboards)
  • Gaming controller repair — Xbox, PlayStation, and Switch controller indicator LEDs
  • Scale modeling and dioramas — excellent for HO and larger scale builds, cosplay wearable electronics, and prop lighting
  • Arduino and maker projects — easiest SMD to hand-solder for custom indicator boards and project enclosures
  • Automotive cluster repair — some newer vehicle instrument clusters use 0805 indicators alongside PLCC-2

*Use 15V instead of 12V for vehicle/alternator sources to account for charging voltage (13.8–14.4V).

DC power recommended: LEDs are designed for DC. Running on AC will cause flickering and reduce lifespan. If you're using a low-voltage AC source — such as a model railroad transformer output or DCC track voltage — convert it to DC first with a bridge rectifier.

About true UV LEDs: This LED emits genuine ultraviolet light at 395–405nm. To the human eye, true UV often appears as a deep blue or blue-violet hue rather than a vivid purple — this is normal and expected. The perceived color can change depending on what the UV light is shining on (fluorescent materials will glow brightly) and the ambient lighting in the room. In a dark room, the LED looks blue-violet; in a lit room it may appear dimmer than other colors because most of the output is in the invisible UV spectrum. True UV LEDs also have lower visible light intensity than other colors — this is inherent to the wavelength, not a defect. If you want a visibly bright purple without UV properties, see our diffused purple LEDs.
